Ideas for Progress: Range 16–19

ACT Explore/ACT Plan/The ACT Mathematics

Entries followed by a dagger (†) apply to the ACT Mathematics Test only.

To enhance their skills in each mathematics-related strand, students who score in the 16–19 score range may benefit from activities that encourage them to do the following:

Score Range 16–19
Basic Operations & Applications
  • solve routine arithmetic problems that involve rates, proportions, and percents
  • model and solve problems that contain verbal and symbolic representations of money
  • do multistep computations with rational numbers
Probability, Statistics, & Data Analysis
  • interpret data and use appropriate measures of central tendency to find unknown values
  • find the probability of a simple event in a variety of settings
  • gather, organize, display, and analyze data in a variety of ways to use in problem solving
  • conduct simple probability experiments, use a variety of counting techniques (e.g., Venn diagrams, Fundamental Counting Principle, organized lists), and represent results from data using different formats
Numbers: Concepts & Properties
  • apply elementary number concepts, including identifying patterns pictorially and numerically (e.g., triangular numbers, arithmetic and geometric sequences), ordering numbers, and factoring
  • recognize, identify, and apply field axioms (e.g., commutative)
Expressions, Equations, & Inequalities
  • create expressions that model mathematical situations using combinations of symbols and numbers
  • evaluate algebraic expressions and solve multistep first-degree equations
Graphical Representations
  • sketch and identify line segments, midpoints, intersections, and vertical and horizontal lines
Properties of Plane Figures
  • describe angles and triangles using mathematical terminology and apply their properties
  • find area and perimeter of a variety of polygons by substituting given values into standard geometric formulas
  • evaluate polynomial functions that use function notation†
  • distinguish between range and domain†
